hiii
i had used this amp earlier but now when i rebuilt it is sort of humming when no input is give and volume is at max, ( speaker kept next to ear)
and i ahve toriod transformer , 2 4700/35v caps per rail and 104 poly cap on the ic about 4 mm away frompin
posted the pcb, it is made as per the datasheet only change is i dont have mute circuit and my feed back resistor for gain are on the tother side complared to datasheet
help needed
